During 2007, 91 ESRD patients receiving PD were studied using dental examinations at our outpatient clinic.
The prevalence of TP was 41.7%(n = 38). Most cases of TP were < 2 cm in size (81.6%) and spindle-shaped (78.9%). The duration of PD was statistically higher in patients with TP size > 2 cm (6.8 卤 3.6 years) than patients with TP size of < 2 cm (3.5 卤 2.6 years).
The higher prevalence of TP and different TP shape (spindle) in comparison with our previous study and the significant relationship between duration of PD and TP size might be due to an underlying disorder, such as renal osteodystrophy.
